Maintenance
Always clean off any liquid as soon as it is spilt. This will
prevent food remains from sticking to the hob surface and you
will save yourself any unnecessary effort.
Never slide pans across the glass surface, as you may scratch
it. In addition, try not to drop heavy or sharp objects on the
glass. Never strike any part of the hob.
Grains of sand that may come from cleaning fruits and
vegetables will scratch the glass surface.
Melted sugar, or foods which contain a lot of sugar which may
have spilt, should be cleaned off the hotplate immediately,
using the glass scraper.
